Modularized code into multiple files.

Added gamemode stubs, iconify support, joystick stubs.

Fixed color index mode, added 8 bit alpha blending, enabled cmaps even
with 15, 16, 24, and 32 depths as some fbdev drivers need this.

Fixed compiling with -ansi

Using SIGIO for keyboard input, so that vt switching is enabled even
if the program is locked.

Fixed numerous small bugs.
